Shameless plug - if you can't remember the URL it's on cresby.com
I once wrote a canal song - never sung it in public - the right moment never seemed to come along. It was about Caggy Smith who still used a horse in the early 70's and apparently replaced it when that one died. Horse drawn allowed full length butties and only one pass through the locks.
Anyone have any info on Caggy Smith who was based on the Warley side of West Brom. I'm thinking Great Bridge for some reason.
